1. Accuracy evaluation of tridimensional images performed by portable stereophotogrammetric system
Resumo Introdução A configuração e o formato das estruturas craniofaciais, a oclusão dentária, a musculatura orofacial bem como a harmonia facial são determinantes para as características próprias da face humana. Instrumentos manuais como paquímetro e fitas métricas têm sido tradicionalmente utilizados para realizar as medidas antropométricas,

3. An efficient general curvilinear coordinates finite element method for the linear dynamic study of thickness-independent shells
Abstract yyTo date, a large number of finite element methods have been developed to study the dynamics of shell structures. Most of them are generally based on the degenerated solid approach and other less in shell theories, but introducing, in this last case, some assumptions to analyze this problem: some of them refer to shallow shells (slightly curved she

4. Structural Health Monitoring of Sandwich Structures Based on Dynamic Analysis
Abstract This work aims to contribute to the development of SHM systems based on vibration methods to be applied on sandwich structures. The main objective is focused on experimental damage identification via changes in the Frequency Response Function (FRF) with the usage of damage metrics. Specimens of sandwich structures made from skins of epoxy resin rein

5. Reappraising the dimensional structure of the PTSD Checklist: lessons from the DSM-IV-based PCL-C
Objective: The dimensional structure of posttraumatic stress disorder (PTSD) has been extensively debated, but the literature is still inconclusive and contains gaps that require attention. This article sheds light on hitherto unvisited methodological issues, reappraising several key models advanced for the DSM-IV-based civilian version of the PTSD Checklis

6. Optimizing similarity queries in metric spaces meeting user\ s expectation / Otimização de operações de busca por similaridade em espaços métricos
The complexity of data stored in large databases has increased at very fast paces. Hence, operations more elaborated than traditional queries are essential in order to extract all required information from the database. Therefore, the interest of the database community in similarity search has increased significantly. Two of the well-known types of similarit

7. Função de avaliação dinâmica em algoritmos genéticos aplicados na predição de estruturas tridimensionais de proteínas / Genetic Algorithms with Dynamic Fitness Functions Applied to Tridimensional Protein Structure Prediction
The protein structure prediction can be seen as an optimization problem where given an amino acid sequence, the tertiary protein structure must be found amongst many possible by obtaining energy functions minima. Many researchers have been proposing Evolutionary Computation strategies to find tridimensional structures of proteins; however results are not alw

8. HydroPaCe: uma metodologia para análise de inibição cruzada em serino proteases através de centroides de regiões hidrofóbicas
Interfaces of protein-protein interactions contain important information about molecular recognition. This work aims at the discovery of conserved patterns in this region. We believe it is essential to understand how substrates and inhibitors are bound and for predicting molecular binding. When an inhibitor binds to enzymes with different structures, sequenc

9. CALCULUS OF AFFINE STRUCTURES AND APPLICATIONS FOR ISOSURFACES / CÁLCULO DE ESTRUTURAS AFINS E APLICAÇÃO ÀS ISOSSUPERFÍCIES
Differential Geometry provides a set of measures invariant under a set of transformations, in particular rigid, affine, and projective. The invariants by rigid motions are using almost all applications of computer graphics and geometric modeling. The affine case, since it is more general, allows to extend these tools. In this work, geometric properties are p

10. Estrutura Cognitiva para Tecnologias Educacionais Construtivistas ECoTEC e seu Instrumento de Otimização Web-ECoTEC
This research developed a method of evaluation for computer tools for education (FCE), called Structure Cognitive for Education Technologies Constructivists (ECoTEC). This methodology detects the construction of structures of logical-mathematical thinking through the proposed activities on FCE. In the ECoTEC conception was used a strategy of analysis which i

11. Orchidaceae nativas da região central de São Paulo, Brasil : florística, interação com forófitos, proposta de novas espécies e propagação in vitro de uma espécie ameaçada de extinção / Native Orchidaceae of the central region of São Paulo, Brazil: floristic, interaction nested with host tree, new species proposed and in vitro propagation of threatened of extinction species
Aiming to know the sorts of Orchidaceae of the central region of the State of São Paulo, from 1996 and more intensively from 2005, visits were carried out in 125 forest fragments of 23 local municípios, with weekly periodicity and also, fortnightly. The collect were assistematics, being each fragment visited in the biggest number of points. The species not

12. Structural health monitoring of composite materials subjected to impacts using the electromechanical impedance technique / Monitoramento de integridade estrutural de materiais compostos sujeitos a impactos empregando a técnica da impedância eletromecânica
Nowadays, composite materials have increasingly replaced traditional materials in applications that require improved performance, safety, economy and durability. Nonetheless, such materials exhibit complex damage mechanisms that cannot be easily detected in early stages. Failures can occur during manufacturing, operation or even in the course of maintenance.
